Interesting, isn’t it? I haven’t slowed it down, but my immediate recognition when I first saw the video was legs and either a jacket or skirt sticking out at the back. If it’s a skirt sticking out at the back, it’s almost certainly Libby, as that night was freezing in Hull so it would’ve been someone in partying clothes. If it is a skirt we see, considering she was wearing a skirt, in conjunction with the timing and location, I would say it’s almost certainly her. If it’s a jacket we see in the video, it’s not quite so refined. Nevertheless, the style of the jacket is obviously short (somewhat cropped above the rear, as we can see when the legs are bent) and so I would identify it as a stiff fashion jacket; some might say a leather jacket.
